World leading seismometers and accelerometers
We have been providing our revolutionary broadband seismic instrumentation to the research community for more than 30 years. Our instruments have underpinned countless research projects over the years, and this in turn has directed the development of our product range. We have equipment suited to both permanent and temporary arrays that can be used for earthquake, aftershock and volcano monitoring. Our instrumentation is also used to monitor triggered and induced seismicity resulting from human actions across a range of industries.
Güralp has been designing and manufacturing revolutionary broadband seismometers and accelerometers for more than 30 years. Our seismic sensors are used worldwide by academic, public, governmental and private organisations to understand and explore our world.
Güralp broadband instruments record seismic events and signals of all kinds, from teleseismic events occurring on the other side of the planet, to microseismic events such as those induced by unconventional hydrocarbon extraction (e.g. hydraulic fracturing).
Our range of OBS have been developed and enhanced over thirty years, with options for virtually every deployment scenario.
Tried and tested on successful deployments all around the globe, ours is the most comprehensive range of cabled and portable ocean bottom instruments available.
As well as housing truly broadband, triaxial sensors to capture the full seismic frequency range, a must for all seismic monitoring applications, we can also integrate additional sensors and gauges, vastly extending the application and capability of our OBS systems.
The revolutionary Aquarius is an evolution of our Liber ocean bottom seismometer, utilising acoustic telemetry capability to deliver near real-time seismic data from the ocean floor to the surface without cables.
Aquarius is a stand-alone free fall OBS with acoustic data telemetry for deployments at depths of up to 6000m.
The system is available in two variants depending on the application and required timescales between battery charge.
Aquarius – for seismic research, when data transfer is needed only at the installation
and at the recovery of the OBS
Aquarius+ – for seismic research and alert, when data transfer is required either on trigger, or on demand at any point during the deployment window
Both systems are equipped with a digital feedback tri-axial broadband seismometer, operational at any angle and with a configurable long-period corner. A three-axis magnetometer and a MEMS accelerometer record the seismometer’s 3D position on the seabed for data rotation during post-processing.
A real-time cabled OBS that sits fully or partially buried on the seafloor for depths of up to to 6000 m/19,685 ft
Depending on the deployment depth, housing is either duplex stainless steel or titanium to protect against corrosion. The unique spherical shape of the casing protects the instrument at high pressures, and an underlying metal plate ensures optimum ground coupling. An optional concrete dome hood can be employed to reduce noise and protect against trawling in shallower waters.
An integrated state of the art Güralp Affinity digitizer delivers data in real-time to the cable system. The frequency range of the sensor can be engineered to suit the requirements of the project. If more than one response range is required, additional sensors or hydrophones can be incorporated. Non seismic sensors, such as absolute pressure sensors for tsunami early warning can also be integrated.
A real-time cabled OBS, pushed or cored into the seafloor, suitable for depths up to to 3000 m / 9,854 ft*
Housed in titanium or stainless steel, the Maris houses a broadband sensor that is fully operational at any angle to support versatile installations. Insertion into the seafloor minimises ambient noise to produce exceptional data quality and increase trawl resistance in shallower deployments. An internal magnetometer and MEMS accelerometer work together to automatically compensate for tilt and horizontal orientation to deliver high-quality waveforms.
The Maris system can be a single instrument or a string of up to eight instruments and includes the Minimus digitiser, housed in a seperate vessel, to deliver data over Ethernet direct to the cabling system. The Minimus also offers a low-latency mode running causal filters alongside traditional acausal filters for earthquake early warning applications. The frequency range of the broadband sensor can be engineered to suit the requirements of the project.
*Deeper options are available.
A rapid response OBS that is lowered on a winch into shallow water of up to 150 m /492 ft depth
The system is lowered to the seafloor using a winched cable which allows for accuracy of deployment location, whilst avoiding the requirement for specialist deployment vessels. The instrumentation is housed in a protective, waterproof, aluminium casing to protect the instrument from corrosion. On project completion, the system is recovered via an acoustic activated release buoy.
The frequency range of the sensor can be engineered to suit the requirements of the project. A hydrophone is incorporated, alternatively this channel can be used for another analogue sensor like a differential pressure gauge or an absolute pressure gauge.
